There are nine models of Festool mobile dust extractors to choose from, ranging in capacity from 3.3 gallons (the CLEANTEC CT 15) to 12.2 gallons (the CLEANTEC CT 48). The CLEANTEC CT 26 E I sits in the middle of the lineup with a 6.3-gallon capacity. Since the models are quite similar, most of the comments below apply to all of them.

The previous version of this model — the CT 26 — has been available for over a decade, so you might be wondering what’s special about this new version. The answer lies in those two added initials: “E I,” which stand for “Electronic Interface.”

This means the unit includes a Bluetooth module and remote-control functionality, allowing the extractor to be triggered wirelessly — either by a Bluetooth-enabled Festool tool or via a remote switch, like the Bluetooth button on the suction hose. This is especially useful when using cordless tools or working some distance from the extractor. The “E” denotes variable suction control and automatic tool start, while the “I” indicates that the Bluetooth module is included.

So, if you already own a CT 26, there’s probably no need to rush out and upgrade to the CT 26 E I. However, if you don’t have a Festool extractor — and you’re either itching to get one or growing increasingly frustrated with your current non-Festool model — the CT 26 E I will be a breath of fresh air.

The CT 26 E I offers a number of standout features that make it ideal for woodworking and professional shop use.

Appearance & Size
The CT 26 E I features a low-profile, rectangular design (approx. 25″ x 14″ x 22″) that’s far more stable than the typical round-top shop vac. Its low center of gravity, smooth-rolling wheels, and front swivel casters make it nearly impossible to tip over — even when tugging on the hose.

The unit is split into two parts: a top motor and HEPA filter and a bottom dust bag and storage bin. Two durable metal latches keep them locked tight, and the gasketed seal between them keeps dust and moisture out. Inside, the motor is fully enclosed to protect electronics from dust. Ventilation openings under the control panel help circulate air efficiently.

Parking Brake
A foot-activated brake raises the front casters, stabilizing the unit. On rough surfaces, it’s incredibly effective. On smooth floors like my concrete shop, it still performs better than typical caster locks — though some sliding can occur with strong hose tugs.

Power Cord Storage
A 25-foot, 12-gauge power cord offers excellent reach. A rear-mounted cord hook and side clips keep everything neatly stowed when not in use. One of the side clips rotates to make cord removal quick and easy — a thoughtful touch.

Sys-Dock Top & Systainer Compatibility
The CT 26 E I doubles as a rolling workstation. The flat top includes a Sys Dock system for securely latching Festool Systainers — modular storage boxes ideal for tools, accessories, or hardware. Two green locking handles (T-LOCs) make the connection effortless. Even non-Festool users can buy Systainers separately to take advantage of this system.

Hose Garage & Handle
The 4-1/2″ deep top compartment stores the hose neatly and includes a carry handle for easy transport. Whether it’s the standard 1-1/16″ hose or the larger 1-15/16″ version, it fits snugly in the storage cavity. At just over 30 pounds, the extractor is manageable for stairs, van loading or shop-to-jobsite travel.

Anti-Static Hose
The included anti-static hose (1-1/16″ x 11.5 ft) eliminates annoying shocks and static build-up. It’s durable, flexible and resistant to crushing — mine has survived the occasional heavy board, tramping on and daily use without a mark. I haven’t experienced any clogging with the hose, even when  using it my planer or jointer.  Festool’s delayed shut-off clears dust from the hose after power down. Hose changes are quick, thanks to a push-and-pull connection system that provides a snug, leak-free fit.

HEPA Filtration
The HEPA filter captures 99.97% of dust down to 0.3 microns. This is especially important when working with fine dust from materials like MDF or during sanding operations, helping maintain a cleaner and healthier shop environment. Filter removal takes seconds: lift the green lever, pull out the frame, and clean or replace. For routine maintenance, I tap the filter outdoors into a trash can and occasionally blow it out with compressed air. With care, one filter lasts a long time — especially if you use bags consistently.

Self-Cleaning Dust Bags
The CT 26 E I includes a SELFCLEAN dust bag that resists clogging by collapsing slightly when the motor shuts off — causing fine dust to fall away from the inner surface, reducing caking. A built-in rubber gasket prevents dust leaks. The bags fill to the brim evenly without any apparent loss of suction power.

Changing a bag takes less than a minute. A 5-pack (#496187) costs $67. Alternatively, Festool offers a Longlife reusable bag (#496120) rated for up to 500 uses — a significant cost saving if you use your extractor on a daily basis.

Motor and Power Control
The motor draws 10 amps, delivering 138 CFM and 96″ of water lift — enough for nearly any small or medium tool. The front control panel includes a tool-triggered auto-start outlet, adjustable (5-step) suction control, Bluetooth connection button, and manual power switch. Plug in a tool, and the extractor powers on automatically with soft-start protection. The suction dial lets you reduce airflow — I use it to lower air suction when finish sanding — and as a bonus it decreases noise in the shop.

Auto Start Features
One of its most useful capabilities is the tool-triggered auto-start, which powers the extractor on when a connected tool is activated. You can use tools that draw up to 2,400 watts (20 amps). Thanks to its built-in Bluetooth module, it can also be started wirelessly using compatible cordless tools or a remote on the suction hose — making it extremely convenient when working away from the unit.

Wet Extraction Capability
Although I haven’t tested it for wet vacuuming, the CT 26 E I includes an automatic water shut-off sensor to prevent overfilling. Just remove the HEPA filter and install a wet filter (#496169). The sealed housing keeps everything protected.

There are other optional accessories that increase the functionality of the extractor. They include hose reducers and extensions, cleaning nozzles, blast gates, tool holders, and a cyclone separator.

Performance & Verdict
After two months of use, I can confidently say the CT 26 E I HEPA extractor is a pleasure to work with. It’s quiet, stable, well-built, and highly effective — especially paired with Festool tools. As well as using the extractor connected to my sander or router, I use it extensively with a Festool mitre saw and plunge saw to process sheet goods and rough lumber before final dimensioning on the table saw. This is a combination made in heaven. A lot easier on my back, and the extractor picks up 80 percent or more of the dust. When connected to my random orbital sander the extractor seems to pick up just about all the dust.

Pros:
✔ Outstanding dust containment
✔ Smooth auto-start operation
✔ Smart storage and design touches
✔ Long cord and hose length
✔ HEPA filtration
✔ Bluetooth connectivity

Cons:
✘ Hose is stiff and can be hard to maneuver
✘ Bags fill quickly with planers or jointers
✘ Pricey compared to traditional shop vacs

Overall, the CT 26 EI is a premium tool that lives up to its price tag.  If you’re looking for a vacuum simply to clean up the shop floors, then it’s probably not the solution for you. However, if you are looking for a highly reliable and efficient tool that does a great job of managing dust in the shop or an on a job site, it’s an investment in cleaner air and a better work environment.

Cost of Ownership

The CT 26 EI costs $1145 (plus taxes and delivery if you can’t pick one up locally) and comes with an anti-static hose, main filter and one self-cleaning filter bag. On average, I’m in the shop 30 hours a week, and the CT 26 EI is my only dust extraction system, so it gets a lot of use. If it lasts the duration of the warranty (3 years), my annual cost of ownership (less consumables) is about $380. Given the reputation of Festool, and my personal experience with their products, I think it reasonable that I’ll get at least 10 years from the unit, which works out to $115 a year. And, if you run a woodworking business, you can claim a 20% capital cost allowance. Factoring in its small footprint, the ease of quickly connecting it to different tools, the convenience of transporting it to a work site, it’s efficiency in sucking up dust, the relatively low noise level, and it’s overall reliability – the CT 26 IE provides me with good value for my money. While it’s certainly hard not to get perturbed by the initial upfront cost of any premium tool, it’s important to look at the prorated cost over the expected life of the product.
